The fertilizers contain encapsulated solid mineral nutrients that dissolve slowly in water, and are then released into substrates over an extended period of time. Although the use of CRFs is an accepted practice, growers and researchers are always looking for ways to decrease fertilizer and irrigation expenses and reduce the impact of nutrient leaching into the environment. A new study contains recommendations for CRF placement methods that can address these issues.http://phys.org/news/2015-01-fertilizer-placement-affects-nutrient-leaching.html

The treaty signing follows meetings by representatives that have previously agreed to sign it—the signing will be held in Minamat Japan—site of one of the largest mercury spills in history. David Krabbenhoft and Elsie Sunderland of the U.S. Geological Survey and Harvard University respectively, have published a Perspective piece in the journal Science, on the treaty and the many issues surrounding the use of mercury and the problems it can cause. Contributing correspondent for the same journal, Lizzie Wade has also published an article describing the single worst mercury polluting offenders—artesian miners—and the difficulties in getting them to stop their practices.http://phys.org/news/2013-09-minamata-convention-treaty-mercury-pollution.html

Space Exploration Sun, 09 Sep 2012 14:47:28 EDTnews266420842Unusual reaction eschews high temperatures and water to lock carbon dioxide away(Phys.org) -- When it comes to reducing the impact of the energy we use to cool our homes and power our computers, one option is to remove gaseous carbon dioxide (CO2), pump it into underground reservoirs, and have it become part of the mineral formations. If the CO2 doesn't react, it remains in a state that could be released by drilling or earthquakes, defeating the purpose of sequestering the carbon away from the atmosphere. Keeping the CO2 trapped by transforming into minerals, called carbonation reactions, take place much more readily at high temperatures. But, scientists at Pacific Northwest National Laboratory discovered a reaction that breaks the rules. At relatively low temperatures and while recycling the water it needs, this reaction transforms CO2 into the mineral magnesite.http://phys.org/news/2012-08-unusual-reaction-eschews-high-temperatures.html
